App might either not work at all or work differently on phones due to several reasons. Some of them are listed below:
1. You did not have latest/greatest version of official Android Chrome browser before you started installing the app using 'Add to Home screen' - make sure you are on the latest available Chrome version for your phone
2. You have not installed using a stable internet connection - When you hit 'Add to Home screen', the browser gets all the screens of the application from the server and creates a local version of the application. If this process is done using a bad internet connection, there are chances that you will see some screens half made or different from other users phones - please ensure that you have at least a stable 3G speed connection to install the application.
3. You have too many apps running on your phone - please stop or uninstall apps which use up too much resources on the phone
4. You do not have enough storage space on your phone - please uninstall apps which use up too space on the phone
